SELF-OILING ROCKER BEARING.

Application filed May 15, 1919, Serial No. 297,199.

T 0 all to ham it may concern Be it known that I, CHARLES E. THOMP- SON,a citizen of the United States, resid- The purpose of this invention is,as the.

name implies, to provide a self-lubricating rocker-bearing especiallyadapted for reciprocating machinery, such as ore-concentrators. Abearing of this sort is nearly frictionless, which is one of thedesideratums, and one of the features of my present invention is theprovision of a rocker seat or die with the arc upward in order to keepgrit out of the rocker-die.

Other advantages of this invention are the movement in approximately astraight line, and the ease of adjustment of the parts of the rocker.

With the foregoing in view, this invention consists of an adjustablerocker pocket which contains a supply of oil, and in the bottom ofwhichis located a removable convex rocker-die or seat that fits into thelower concaved bearing surface of the rocker, the curvature of therocker-bearing seat enabling the upper end of the rockerarm to oscillatethe distance it has to travel in approximately a straight line.

In the accompanying drawings:

Fig. 1 is a longitudinal sectional view through the rocker-pocket,rocker and rocker-plate, and a frame upon which the pocket is adjustablysupported;

Fig. is a fragmentary view at rightangles to Fig. 1, and one-half ofwhich is in section;

Fig. 3 is a bottom'plan view of one of the rocker-plates;

Fig. 4: is a top plan view of the rocker-seat or die;

Fig. 5 is a side view ofthe same.

The numerals 1 represent two channelirons forming the framework for thesupport of the other parts of the mechanism.

2, isthe rocker-pocket which fits between the channel-irons 1, and therocker-pocket is provided with overhanging flanges 3, which extend overthe channel-irons and the Set-screws 4 screw into threaded holes inSpecification of Letters Patent.

these flanges and are employed for adjustmg and refilling therocker-pocket, after which the pockets are clamped solidly in place byscrewing up the nuts 5 on the clamping bolts 6 located in pairs, one ofwhich is on either side of each pocket.

In the bottom of the pocket, the rockerseat or die 7 is cleta'chablyfitted. This rocker-seat or die is in the form of an upwardly extendingarc, the wear surface of which is preferably chilled. The rocker 8 has aconcaved chilled lower surface, which fits and bears upon therocker-seat or die, as clearly shown in Fig. 1. The rockerplate 9 isadapted to be secured to the deck trace core 10 by bolts 11, which corein turn is secured to the deck stringer 12, as shown in Fig. 2. Thelower surface of the rocker-plate is provided with parallel flanges 13,which receive the steel wearing plate 14 and also the upper end of therocker between them.

This wearing plate is secured in place by the same bolts 11 which securethe rockerplate and deck trace core together.

The pocket is filled or partially filled with oil 0, as shown in Fig. 1,which keeps the parts well lubricated, as the rocker is oscillated, andas the stroke is limited, and the rocker is of considerable length, andits bearing is arcuate or convex, the movement of the upper end whichsupports the table is approximately in a perfectly straight line.

The rocker-bearing has the new and useful function of rocking the tabledeck with little or no friction when compared to a slipper bearing withfriction, and because of its construction does not impart additionalinertia shock to the table deck, the result being that pause anddifferential as delivered by the head-motion intended to be employed forthis hearing are not interfered with.

I claim:

1. The combination of a suitable support, a rocker-pocket detachablyheld by the support, means for adjusting the pocket with respect to thesupport, and means for securing the pocket rigidly with respect to thesupport, when the pocket otherwise shall have been adjusted.

2. The combination of a suitable support, a rocker pocket entirelyclosed except at the top and detachably held by the support and adaptedto contain a lubricant, a

rocker, a rocker-plate resting on the rocker,

and set-screws connected with the pocket and resting on the support foradjusting the pocket. V

3. The combination of a suitable support, a rocker pocket entirelyclosed except at the top and detachably held by the support and adaptedto contain a lubricant, a rocker, a rocker-plate resting on the rocker,setscrews connected with the pocket and resting on the support foradjusting the pocket, and clamping means for securing the pocket rigidlyto the support.

4. The combination of a suitable support, a rocker pocket entirelyclosed except at the top and detachably held by the support and adaptedto contain a lubricant, a rocker, and a rocker-plate resting on therocker, a rocker-seat or die detachably restplate, a wear-plate,'-and adeck trace core 7 secured together, the latter being adapted to besecured 'to the machine to be rocked.

In testimony whereof I aflix my signature.

CHARLES E. THOMPSON.
